Allow rolebinding/clusterrolebinding with explicit bind permission check
Fixes https://github.com/kubernetes/kubernetes/issues/39176
Fixes https://github.com/kubernetes/kubernetes/issues/39258
Allows creating/updating a rolebinding/clusterrolebinding if the user has explicitly been granted permission to perform the "bind" verb against the referenced role/clusterrole (previously, they could only bind if they already had all the permissions in the referenced role via an RBAC role themselves)
```release-note
To create or update an RBAC RoleBinding or ClusterRoleBinding object, a user must:
1. Be authorized to make the create or update API request
2. Be allowed to bind the referenced role, either by already having all of the permissions contained in the referenced role, or by having the "bind" permission on the referenced role.

Add verbs to thirdparty resources in discovery
The namespace controller ignores thirdparty resources right now because verbs are not set. This PR sets a static list of verbs.
Moreover, integration tests are added for the discovery info of thirdparty resources.

Log a warning message when failed to find kind for resource in garbage collector controller
at this time, I do not think thirdparty api group version resources should be taken care by garbage collector controllers, and this line of call will fail actually: https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/garbagecollector/garbagecollector.go#L565, and as a result, the garbagecollector controller failed to start.

Add test for json tags on internal and external types
Follow up from https://github.com/kubernetes/kubernetes/pull/38406
- adds static analysis tests preventing internal types from adding new json or protobuf tags
- adds static analysis tests requiring json tags on external types (and enforcing lower-case first letter)
- fixes issues found by the tests
- move rest handler into handlers package
- move errors into handlers/errors package
- move negotation code into handlers/negotation package
- move http response writer helpers into handlers/responsewriter package
- split up pkg/apiserver/apiserver.go
Note: this is only an intermediate step towards a proper genericapiserver
package hierarchy.

Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.
@kubernetes/sig-api-machinery @deads2k
```release-note
The main repository does not keep multiple releases of clientsets anymore. Please find previous releases at https://github.com/kubernetes/client-go

Remove non-generic options from genericapiserver.Config
Remove non-generic options from genericapiserver.Config. Changes the discovery CIDR/IP information to an interface and then demotes several fields.
I haven't pulled from them genericapiserver.Options, but that's a future option we have. Segregation as as a followup at the very least.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

Remove static kubelet client, refactor ConnectionInfoGetter
Follow up to https://github.com/kubernetes/kubernetes/pull/33718
* Collapses the multi-valued return to a `ConnectionInfo` struct
* Removes the "raw" connection info method and interface, since it was only used in a single non-test location (by the "real" connection info method)
* Disentangles the node REST object from being a ConnectionInfoProvider itself by extracting an implementation of ConnectionInfoProvider that takes a node (using a provided NodeGetter) and determines ConnectionInfo
* Plumbs the KubeletClientConfig to the point where we construct the helper object that combines the config and the node lookup. I anticipate adding a preference order for choosing an address type in https://github.com/kubernetes/kubernetes/pull/34259

convert TPR controller to posthook instead of disable flag
Converts the third party resource controller into a posthook using a loopback client instead going direct to etcd. This let's us eliminate more flags and special-casing during initialization. Also, using a client brings us closer to building this without side-effects for downstream composers.

Change legacy API resource registration
Updates the legacy API resource registration to emphasize its different-ness and to simplify supporting objects. The option has to remain in the genericapiserverconfig for multiple prefixes to enable cases where composers/extenders had composed additional groupless APIs. See OpenShift as an example.
However this is now transparent to "normal" composers.

remove testapi.Default.GroupVersion
I'm going to try to take this as a series of mechanicals. This removes `testapi.Default.GroupVersion()` and replaces it with `registered.GroupOrDie(api.GroupName).GroupVersion`.
@caesarxuchao I'm trying to see how much of `pkg/api/testapi` I can remove.

fix pod eviction storage
Refactor pod eviction storage to remove the tight order coupling of the storage. This also gets us ready to deal with cases where API groups are not co-located on the same server, though the particular client being used would assume a proxy.

Prune unused parameters and call only once

add logging for enabled/disabled API Groups
Adds logging to the apiserver to indicate which API groups are enabled and disabled as go through. This will make it easier to identify what's gone wrong in cases where the API server is down during diagnoses and the config is inaccessible, like in GKE tests. For example https://github.com/kubernetes/kubernetes/issues/32185#issuecomment-245255700 .
